TYPEWBITING MACHINE.

Application led June 14, 1923. `Seria1No.l645,261i. v

To all whom. t concern.' Be it lmown that I, JOHN WALDHEIM, a

citizen of the' United States, residin inl Elizabeth, in the county of Union and tate of New Jersey, have invented certainnew and useful Improvements in 'Typewri'ting Machines, of which the following 1s a specification.

The vinvention relates t0 a machine for typing uon work-webs, comprising several plies, eit er fan-folded or `unattaclied to each other, and lupon each of which plies are usually printed a succession of forms; the form lengths or sections of one ply reg1stering with those 0f the other plies, and carbons being interleaved vwith the plles.'

The work-webs may be continuous, or of 4indefinite length, accordingto the number of forms`which compose the same. Ordinarily, however, or at least until so worn yas to call for replacement," a fixed length'of webs; andtthen to resetthe composite web `for commencement of ty ing on the formand to replace thep aten.-

., Y For 'the purpose, amongothers, of avoid-y ingthe' necessity of lifting the platen preliminary to'shift of the carbons, it has been proposed; to utiliie the backward throw of the carbon-carrier, notto effect the Vform-toform shift of the carbons relatively to the `work-webs, but to draw back the entire compositel web sufficiently to release the carbons from the platen; and then, while hold ing the carbon-carrier, with the carbons, stationary in rearward position, to utilize the platen, by forward rotary movement of the same, to advance the work-webs a form length over the carbons. This being done, the carbonscarrier may be released to per- -mit a further forward rotary movement of theplaten to advance the entire composite.

nextweb to position for commencement of typing onthenewform. f N I' v- An,- object of the present invention is the provismnof means for effectingV this lastmentioned forward throw-of the platen, and forv automatically determining the-eXtent of same; thusl precluding inaccuracies on the part of the operator; and; by 'relieving the operator of thenecessity of care and attenv vComposite webs, of 'the character described, havealso been used in typewritingmachinI having computing attachments. It commonly happens, however, in such machines, that a part of the computing mechanlsm 1s found 'on the back of the machine 1n such posltion as to require a special table structure' or support for thecarbon-carrier, to c learthese computing parts and to permit of movement and adjustment of the same.

A feature ofthe present invention is a carbon-carrier table made substantially straight to provide for free movement of the carbons and `work-webs thereover, and also being of an incline, ,to constitute in effect a y straight-line continuation of the rear papertable on the platen-carriage; so as to prov1de a straig tipath for the web to the platen; thereby eliminatin 'such bending of' the web over the upper e ge of the papertable at the rear of the platen as would interfere with easy relative shift of the carbons and work-webs. l `A further object of the invention is the provision of novel means, for effecting the rearward throw of the carbon-carrier, conveniently operable from the front of the carbon-carrier table, and permitting of such control of the carbon-carrier as to preclude sli of the same down 'the table.

)ther features and advantages will hereinafter appear. l

Upon depression of the keys (not shown) of a typewriter forming part of a bookkeeping machine ofthe Underwood-Hanson type, type-bars 11 are swung upwardly and rearwardly to cause types 12 thereon to engage a cylindrical platen 13, mounted on an axle 14 journaled in a carriage 15, which is supported for sliding movement transversely of the typewriter by means including a rear rail 16 fixed on the typewriter-frame 17. Each type-har in its effective movement actuates the usual escapement mechanism (not shown) and effects a letter-feeding movement of the carriage.

As is usual in bookkeeping machines of the type referred to, the frame 17 of the typewriter is set on the casing 18 of the computing mechanism, and provision is made of means whereby the letter-feeding movement of the carriage will effect denomination-selecting for the computing mechanism. To this end, provision is made of i brackets 19 extending rearwardly from the typewriter-carriage and of rods 20 and 21 carried thereby; Rotatably and slidably mounted on the rod 2O is a denominationselector 22, which may be held in proper letter-space positions therealong by means of `a tooth 23 engaging notches in the rod 21, the selector 22 normally lying in depressed or ineective position. Obviously, a plurality of selectors'may be used. v

Upon a letter-feeding movement of the carriage into a computing zone determined by one ofthe selectors, a :trusto-conical roller 24 on the rear end of the selector 22 will ride up on the conical end of a roller 25, having a cylindrical portion of substantially the length of the computing zone, and cause a tappet 26 on the selector to engage seriatim the forward ends of jacks; 2? of a certain set, to advance seriatim the usual pin-bars by connections (not shown). Provision is made of the usual jack-housing 28 and the usual housing 29 for the thrust-rods (not shown)` by which the movements of the jacksl 27 are transmitted lto the computing insane? mechanism, the housing 29 being connected to the jack-housing 28 at its forward end by any suitable means, and the jacks and 'jack-housing being supported on the typewriter-frame by any suitable means, such as a bar 29a and brackets 29". lThere may be several sets of' jacks, and actuation ot a set of jacks by one selector 22 and not by others may be obtained by arranging the diii'erent sets with the forward ends of the jacks extending to different positions toward the front of the machine, and by arranging the tappets 26' on the different selectors 22 in accordance with the sets of jacks to be actuated thereby. The brackets 19 may also be utilized to support a toothed bar 31, on which may be positioned, at letter-space intervals, tabulator-stops 32 in position to be engaged by counter-stops (not shown), when the latter are lifted by means (not shown). The computing mechanism and the denomination-selecting mechanism, forming part thereof, may be, in general, similar to that disclosed in the patent to Richard M. Becker, No. 1,296,355, granted March 4, 1919.

l A carbon-carrier table 35 extends upward and rearward from the platen-carriage 15, and is secured to the latter 'to move therewith in letter feed and return directions in the following manner. The end pieces 36a of the carriage-frame arev connected by a cross tie or'bar 37: and on the end plates 36 of the case-shift -trame are supported the usual rear paper-table and apron 38. Also secured to the bar 37, by means of screws 39, are a pair of brackets 40, the upper ends of these brackets having ears 41. Rods 42', which `orm the side reaches of the carboncarrier table, have lateral oii'sets 43 which abut the bracket ears 41 andk which are secured to the bracket ears byy screws 44, which thread through the ears andA into the ends of the offsets 43. Su'liiciently above the oii'sets 43, to clear the computing mechanism hereinafter described, is a cross rod or bar 45 which forms the front reach of the carbon-carrier table and which connects the side reaches 42 thereof. rlhe side reaches 42 of the carbon-carrier table are connected at the rear by a similar cross bar or tie 46. Brackets, comprising forward arms 47 and rearward arms 48, support the carbon-carrier table rearward of the platencarriage; the arms 47 and 48 of each of such side brackets having offset ears 4S)y and 50, respectively,` secured by screws 51 chine.

the standards 57. kThe standards 57, one.

at each side of the machine, are secured by screws 59 to a table 60. The table 60 supports the frame 18 of the computing machine; and on this frame 18 is supported the -rnain frame'17 of the typewriting mai The carbon-carrier table is, therefore, supported both fore and aft for movement with the platen-carriage transversely of the table 60 and the machine frame' 17.

The work-web, shown in three plies 62, is led into the machine' upward from the rear thereof over a guide-plate 63 secured to the rearcross-piece of the carbon-carrier table. and thence downward and, forward in the direction of the platen. At or just in front of the guide-plate -63 are side gages v64 for the work-web. These gages are adj ustably set (according to the width of the web) on a rod 65 supported by arms 66 on the rear cross-piece 46 of the 'carbon-carrier table., From the rod 65 the plies of the work-web are led lthrough the carbon-carrier 67, where they become interleaved with the y'carb'ons 68, and are thence led downward andforward over the carbon-carrier table,. and 'oye-r the rear paper-table and apron 3 down behind and' around to the fro-nt ofthe platen. Above the printing line of the platen, the Work-webs pass'between the platen and a knife 69' carried yby the side pieces of t-he platen-frame. Above the knife 69, the side pieces of the platenframe are connected by a crow-plate 70, to'

which is.se,cured a staff 71jhavin a gage 72 adjustablyl secured thereto. s indicatedy yin, Figure ythe purpose of this gage isfto posit-ion Ltheleadi11g ends .of the-work- Iwebs at certain-times 'in the operation of the machine. y x

The carbon-carrier carriage consists of a .base-plate?` 73 having on. the. under face fth'e'r'eof two at each side, rollers 74 grooved, ,t6 receive, andy ride upon, rails 75, one at each. side of the carbon-carrier table; the

,rails 7 5 being secured to and extending 1on- .gitudi'nally ofthe side reaches 42 of the carbon-carrier table on the upper side of' the latter. On the carbon-carrier base-plate 73. one at each side thereof, is a standard I76;` the standards 76 'being stepped, as :to the bon-sheets 68. As shown, in\Figure 1, the` work-webs are spread at the"carbon-carrier by the `blades 77 so as to be freely inter` leaved with the carbon-sheets.

' bon-carrier table.

It will be understood that when the composite web, consisting of work-sheets and interleaved carbon-sheets, is in such pos1- tion that the carbons are held to the platen by the usual front and rear feed-rolls 78, the line-feed movement of the platen, in the typing of a form, results in a downward and forward feed of the composite web, such that the carbon-carrier is corresponding-ly fed downward and forward on its rails 75 on the carbon-carrier table. This movement of the carbons with the carboncarrier and with the work-,webs proceeds until the writing of a form is complete.

On completion of a form, it becomes necessary to shift the carbons rearward relatively to the work-webs to withdraw the carbons fromvthe typed form-and interleave the same with the succeeding untI ped form. For this purpose, the'feed-rolls 8 are first thrown olf the platen to release the carbons to rearward movement. The mechanism for throwing otl' the feed-rolls may be that found in the Underwood standard typewriting machine, and consisting of a fingerpiece 79`connected-with a link 80 for turning a. shaft 81 having flats for spreading apart arms 82, which carry the feed-rolls and which are pivot/ed on lanother shaft 83; theshafts 81 and 83 being mounted in the sideplates of the platen-frame. When the feed-rolls are thrown olf, the carbon-carrier 67 may be moved backward from Figure 5 Ato Figure 1 position without tearing the carplaten. The backward movement of the carbon-carrier from Figure 5 to Figure 1 posit-ion is effected by the following means.

The upper and lower, or rear and vfront edges, of the base-plate 73 of the carboncarrier 'are connected by loops 84 and 85, respectively to a belt 86, which is thereb made endless, and which passes over a pu ley 87 at the upper rear end of the carboncarrier table and a pulley 88 at the lower forward end of the carbon-carrier table. Both pulleys 87 and 88 are shown as having teeth 89 to engage in holes 90 in the belt 86. The upper pulley 87 is an idler on a stub-shaft 91 journaled in a bracket 92 secured by screws 93 to the under side of the carrier table rear rail 46. Pulley 88 is fast to a shaft 94l journaled at one end in a bracket 95 at the left-hand side of the kcarbon-carrier table and at its other end to a bracket 96 att-he right-hand side of the car- The `bracket 96'is an L- shaped plate secured by screws 97 on the upper side of the YL-shaped portion 42-43 of the side piece of the carbon-carrier table;

and having an offset and downwardly depending ear 98 in which the end of the shaft 94is set. A collar 99`secured to the shaft 94 holds the latter against rightward displacement on the bracket ear 98. The left-hand bracket 95 comprises a plate 100 set at some distance to the left of the lefthandv tableyreach 42 and having an ear 101 offset therefrom and secured to the under side of the left-hand table bar 42. A-t its forward end the bracket-plate 100 has an offset 102 which is secured by screws 103 to the upper side of the L-shaped portion 42-43 of the left-hand table bar 42. l

AOn a hub 104 secured by a setfscrew 105 to the shaft 94 at the right-hand side of they 'bracket-plate 100 is a pinion 106 meshing with a pinion 107 secured by a setscrew 108 to a stub-shaft 109 also journaled in the bracket-plate 100 at the righthand side thereof. Fast to the stub-shaft 109 at the left-hand side of the bracketplate 100 is another pinion 110 in mesh with an arcuate rack 111 secured by screws y 112 to a handle 113; the latter being pivoted at 114 to the bracket side plate 100. In

order that the'handle-arm 113 may be swung Without striking the pinion 110, the rack is offset leftward at 115 where itv connect with the handle 113; i

From the above connections, it will be seen that, if the handle 113 is swung from Figure 5 to Figure 1 position, the rack 111 will rotate the pinions 110 and 107 clockwise (Figure 5)- to cause the pinion 106 to turn counterclockwise (Figure 5), and thereby, through the pulley 88, to drive the belt in such direction as to move the carbon-carrier upward and rearward on the carbon-carrier table. A stop 116 on one of the side reaches 42 of the table, by engagement of the upper edge of the base-plate 7 3 of the carbon-carrier, may determine the upper, or Figure 1 position of the latter,

and consequently the throw of the latter necessary to clear the leading edges of the carbons from the platen. Tendency of the carbon-carrier to slide down the table may be resisted by a coil spring 117' on the shaft 94; one end ofthe coil spring being connected to the pulleyL 88 and the other end to the bracket 98.y The carbon-carrier will, of course, be held in Figure 1 position so long as the handle 113 is held by the operator in its Figure 1 position.

)Vhen the composite'web is in position, with the carbons free of the platen, a shift of the work-webs with respect to the car'- bons may he effected. To this end, the pressure rolls are re-applied to the platen, and, with the carbon-carrier heldk in its Figure 1 position, whether by the spring 117, or more assuredly by the handle 113, the platen is rotated forward to' bring the leading ends of the work-webs to the gage 72.

The position of this gage determines a forf ward movement of the work-webs, equal to one (form length, with respect to the carwheel 119 forming part of the line-spacing mechanism.

- It now remains to set the composite web to osltion for commencement oftyping on a resh form, Such a positioning of theV composite web must ordinarily be a definite movement, and must certainly be a movement suiiicient to bring the leading edges of thecarbons to the printing lines, from Figure 6 to Figure 7 position. In Figure 7 position of the composite web, a previously-typed form may be det-'ached by drawing the work-webs against the knife blade 69.

As hereinbefore stated, the present invention embraces means for determining automatically the precise movement of 'the platen re uired to feed the web from Figure 6 to4 igure ,7 position, ,to set the same in proper position for commencement of typing, and to position the previously-typed form correctly for removal of the same by means of the knife 69., as shown in Figure 7. vlhis means (see Figures 3 and 2) coinprises a pinion 120 loose onthe platen-axle 14, and a ratchet-wheel 121 made fast to the' platen-axle by means of a key 122. Also supported by, but disconnected from, the platen-axle is a plate or bracket 123. Anarm 124 secured at 125 to the plate 123 and at 126 to the right-hand side plate 36 of the platen-frame holds the plate 123 against angular displacement. Pivoted at. 127 on the plate 123 is an arm or handle 128 which carries a rack 129 in mesh with the-'pinion 120. Fast to the pinion 120 is an arm 130, on the end of which is pivoted a pawl 131 for engagement with the teeth of the ratchet-wheel 121. A spring 132 tends to throw the pawl into engagement with the ratchet-wheel. A stop-pin 133 on the plate 123, however, in the Figure 3 position of the parts, by engagement with a tail piece 134 on the pawl, disengages the pawl from the ratchet-wheel and holds the same free therefrom against the. action of the spring 132; this` being the normal or idle position of the parts. To turn the platen, to feed the web from Figure 6 to Figure 7 position, the arm 128 is pulled forward from its full-line Figure 3 to its dotted-line Figure 3 position. This movement of the arm causes the rack129 to rotate the pinion 120 in clockwise (Figure 3) direction with the arm 130 and pawl 131. As soon as the pawl leaves the pin 133 it engages the ratchet-wheel 121, andthe latterlbeing secured to the platen-axle, carries with it the platen.

This forward rotary movementl of the platen continues until the pawl strikes another stop-pin 135 on the plate 123; whereupon movement of the parts is arrested with the handle in Figure 3 dotted-line position and the web in Figure 7 position. At the time the handle 128 is thrown forward the handle 113 stands released, and the carbon-carrier 67 moves down the table a distance commensurate with the advance of `the carbons from Figure 6 to Figure 7 position. f Thereafter, in the line-spacing operation in the typing of the form, the carbon-carrier continues to move down the table until typing on the form is completed. The arm 128 may be automatically returned to normal (Figure 3) position by a spring 136.

It will be noted that the position, length, and shape of the brackets 40 issuch as to clear the denominational selector 22 and the jack-housin 28 and to support Athe carboncarrier tab e clear of the denominational selector and jack-housing. It will also be noted that the position of the first crossbar 45 of the carbon-carrier table ,is such as to permit upward swing of the selectors for adjustment thereof.

It will beiseen from Figures 1 and 5- that the incline of the carbon-carrier table is such as to make it practically a straight- -line continuation of the rear paper-table on the platen-carriage; so that, without bending, the web passes from the top of the carbon-carrier table to its pointof engagement with the platen. p

Variations may be resorted towithin the scope of the invention, and portions of the improvements may be used without others.
